LRP Sphere 2007 MODE button faulty

[Fiddybux]

The mode button on my 2007 LRP Sphere is playing up.

I can push and push and it only registers say 1 out of 5 goes, this makes changing modes a real pain.

Can I get this done under warranty and to whom should I send it?

Checked the LRP website and there is no email address on there for advice.

Thanks.
